*Significant difference between groups at this time point (P < 0.05).
a
For MICT, ‘bouts’ refer to the time periods corresponding to the interval periods of the HIIT protocol.
b
P values from the two‐way ANOVA are listed in the order: main effect of bout, main effect of group, and the interaction between bout and group.
Values are the mean ± SEM (n = 10).
